Hadoop 3.3 brings a few Jetty dependencies which transitively brings in org.ow2.asm:asm-analysis, org.ow2.asm:asm-commons, org.ow2.asm:asm-tree.
When testing with the latest Jetty (9.4.26.v20200117) I found its org.ow2.asm:* updated from 7.1 to 7.2, which changed the declared license from "BSD" to "BSD-3-Clause License" (The actual license text did not change). The HBase's license checker doesn't accept it.
File the jira to update it to "BSD 3-Clause License" so that HBase can build.
